Product Overview
ULN2003A is a high-voltage, high-current darlington array containing seven open collector darlington pairs with common emitters. Each channel is rated at 500mA and can withstand peak currents of 600mA. Suppression diodes are included for inductive load driving and the inputs are pinned opposite the outputs to simplify board layout. Device interfaces to all common logic families: 5V TTL, CMOS. It is useful for driving a wide range of loads including solenoids, relay DC motors, LED display filament lamps, thermal printheads and high-power buffers.
- Output voltage of 50V
- Integrated suppression diodes for inductive loads
- Outputs can be paralleled for higher current
- TTL/CMOS/PMOS/DTL compatible inputs
- Input pins placed opposite to output pins to simplify layout
- 0.9V typical collector-emitter saturation voltage at IC = 100mA, IB = 250µA
- 0.93mA input current I(ON) at VI = 3.85V
- 2.4V input voltage at IC = 200mA
- 0.25µs turn-on delay time and turn-off delay time at 0.5 VI to 0.5 VO
- DIP-16 package, operating ambient temperature range from - 40 to 85°C
